I just did the pidigits one in about 5-10 minutes... and Robert Bradshaw just walked into my office and said he's already done some of them (they are sitting on his laptop somewhere). http://sage.math.washington.edu/home/wstein/tmp/pidigits.pyx The timing for that one is basically the same as C. Robert remarks that in some cases Python's "print/rawinput" is a serious bottleneck compared to C if we want to stick with idiomatic Cython.
